Agree with webber286, the conversion rate in sports betting is low. Simon Eaton from 9am has mentioned it before when comparing sports bettors and casino players noting that the conversion rate for sports bettors is much lower while an average “life span” for a sports bettor is longer.
For me it the conversion rate has been over 300 clicks per a depositing player at Bet Royal. Have no real players through 9am despite many hundreds of referrals.
I have tried PPC for a non gambling related web site, it did not work at all.
We’ve used Yahoo Search Marketing UK and have given them evidence of fraudulent clicks. They claimed they would investigate the matter and have never returned our follow up attempts. You should either stay away or at least stay off the main terms.
